Cochrane review on masks

The Cochrane review on masks was recently discussed. Steven Novella has posted an analysis on Science-Based Medicine:
https://sciencebasedmedicine.org/masks-revisited/


"This recent Cochrane review is very limited in scope and is highly problematic in its methods. The most we can conclude from it is that we need better and more relevant controlled trials of mask wearing to more precisely determine its effect on the spread of COVID. But it does not show that mask wearing does not work or that mask policies don’t work. Further, if we look at the totality of the evidence (not just these trials) the best current conclusions are:

"Properly wearing face masks when in public during high risk of spread reduces the risk of spread of respiratory viruses in general and COVID specifically.

"During a pandemic of a respiratory virus, mask mandates are an effective public health measure.

"N95 masks likely offer the best protection, but need to be worn over the mouth and nose to be effective, and need to be worn continuously when in public (not just in targeted situations)."
